孔喉中油基泡沫的流动特性与稳定性分析
Flow characteristics and stability analysis of oil-based foam in pore-throat structures
摘要
Abstract
Oil-based foams hold significant potential for enhancing oil recovery and regulating subsurface fluid flow,yet their stability under high-temperature reservoir conditions and their transport mechanisms within pore-throat structures remain insufficiently understood.To address this gap,this study systematically investigates the behaviour of an oil-based foam system through temperature-dependent stability experiments,complemented by pore-scale numerical simulations that characterize bubble deformation and breakthrough within porous media.Experimental results show that increasing temperature accelerates liquid drainage and gas diffusion within the foam films,leading to a reduction in the number of bubbles,enlargement of average bubble size,and a pronounced decline in overall foam stability.Simulation results further demonstrate that pore-throat diameter and injection pressure jointly govern bubble morphology evolution and breakthrough behaviour,with the competition between capillary forces and external driving pressure emerging as the key mechanism influencing oil-based foam mobility.By integrating these findings,this work establishes a unified mechanical framework linking temperature effects and pore-throat confinement,thereby providing theoretical support for the application and optimization of oil-based foams in high-temperature reservoirs.关键词
